The mechanical thermostats temperature sensing switches supplied with most boat refrigerators work fine for two years or so. After replacing our mechanical thermostats at roughly two-year intervals, I finally wised up and inquired about an electronic replacement. Carel, an Italian company, manufactures a very nice electronic thermostat. This device can be ordered from www. The installation and operating instructions can be downloaded from this website if you would like to have a detailed look before ordering. Making the connections Installation is straightforward. Inside of the old mechanical thermostat you will find a small resistor in one of the wires. This resistor determines the speed of operation of the compressor. Remove the resistor from the old thermostat and connect it and the two wires to the new electronic thermostat terminals 1 and 2. Mount the electronic thermostat outside of the cooled space where the temperature display can be easily seen. A small bracket made of aluminum or plastic will make a neat job of it. R-Parts even sells a kit that includes the mounting bracket, fuse holder, etc. The temperature sensor should be mounted in free air space near the evaporator, but not touching the evaporator wall as was the old sensing tubing. Route the sensing wire where it will not be easily damaged. Keep it clear of main power wiring, as it is very sensitive to interference. Connect the sensor wires to thermostat terminals 7 and 8. This electronic thermostat can operate on 12 to 24 volts AC or DC. Be sure to install an in-line fuse of milliamps in the positive lead. Note that as the thermostat will operate on AC or DC, the device is not polarity-sensitive. I connected the volt DC positive lead to terminal 4 and the negative lead to terminal 5. The thermostat is quite susceptible to radio frequency interference, however. If you notice that your refrigerator compressor turns on each time that you transmit on your SSB radio, then simply add a snap-on ferrite available from Radio Shack around the wire from the thermostat to the compressor and around the temperature sensor wire. Try one ferrite around both wires at first, but under no circumstances include the power wires in the ferrite. Read the directions carefully before powering up the thermostat. The thermostat can be configured to display degrees Fahrenheit or Celsius. We chose degrees Celsius because at a quick glance 0. To ease your task, R-Parts has a configuration guide at www. Note that some of the settings are default values, so just skip over them. Our first electronic thermostat performed flawlessly without the slightest bit of attention since we installed it in November It somehow received a few drops of salt water during our Atlantic crossing, and failed shortly after arriving in Puerto Rico. We located this suitable replacement from R-Parts. The temperature display is most reassuring, and can be read from across the boat. The very thin walled aluminum evaporator is subject to corrosion when at room temperature. So, keep it cold: We usually get about six years of full-time use.
